I bought the Helim a few weeks ago and love it! I really can't find anything wrong with it yet. It is very easy to pull back and very smooth shooting. I've heard people say things about hand shock and vibration after the shot but I have not felt anything like that. Once the sight, stabilizer and arrow rest is on I think it really absorbs everything so I never had a problem. Once I had it sighted in the groups are really tight. I'm shooting 3 inch groups at 35 second time out and looking to get all set up to 45 yards this weekend. It can shoot consitant even beyond that but I don't have any shots longer than 45 so I'm quite happy with that.
